EPDM closed-cell elastomeric foam insulation

Uniquely formulated for success

The difference is EPDM

It’s what makes roofing material able to withstand years and years of extreme sun, heat, snow and rain… . It’s in windshield wipers, car gaskets and any number of products that require extraordinary stability in harsh environments… . It’s Ethylene Propylene Diene Monomer, also known as EPDM, and it’s what gives Aeroflex insulation its extraordinary durability, even in the most demanding environments and applications.

High-end moisture protection at standard costs
Aeroflex insulations provide excellent protection against all types of moisture intrusion -- even in tropical environments and applications with high indoor humidity. Aerocel® ULP® (ultra-low permanence) insulation provides moisture resistance comparable to expensive cellular glass and has the lowest elastomeric permeability rating in the industry at 0.01-perm-inch!
